Weapon restrictions are probably the best idea to go by if you want some challenge. Plus, I don't exactly need achievements to know that I've done something worthy of mentioning. Then again, I take challenges in stride and just to do them for fun where as if you present these same challenges to others, they may simply say that its horrible.
Edit: Speaking of which, I'm actually doing a "No Bullets" hardcoe character right now. Just gotta play my cards right and I'll definitely enjoy it. I know I will. This is excluding the bullets in the tutorial sadly as you're required to knock down 3 bottles with the Varmint Rifle.
Never thought about it that way, that does seem fun! The key to do that is to have a high charisma + intelligence + luck, everything else can remain low. Major skills are barter, speech, lockpicking, sneak. Sounds pretty fun, I'll definitely have to give that a go. But now I need to remake my previous character
which really svcks but now that I know all of the quests I can breeze through it and save maybe 6-8 hours?
